England goalkeeper 'Robbo' and Welsh midfielder 'Digger' are set to line-up against each other in the World Cup qualifier at Old Trafford.
It's the first meeting between the sides for 20 years and a crucial World Cup qualifier and both players admit it's the sort of game they dreamt of playing in as youngsters.
Simon said: "I'm sure we'll all get mixed up with the emotions of it because it will be a great game to be involved in.
"It's one of those games you dream about as a kid. That's the way it is for all the Welsh lads. None of us has played against England before. Hopefully, if I'm playing, will be great to be part of it."
Robbo was handed the England number one shirt by Sven Goran Eriksson for the last World Cup qualifier against Poland and expected to hold onto his position this weekend.
"It will be a difficult game and everyone said as soon as the group was drawn that the home nations against each other would be tough.
"It will be very enjoyable. Every kid growing up dreams of playing for their country and to run out at Old Trafford in front of all the England fans playing for your country in such a big game is a massive achievement."
Friends and team-mates Simon Davies and Paul Robinson will become enemies for 90 minutes when Wales play England on Saturday - but they both agree on one thing.
